Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pouring material filling device for filling a bottom portion of a ladle with a casting material such as castable and repairing the damaged portion.

[0002]

2. Description of the Related Art In a ladle, when hot water such as molten steel is received inside, the hot water hits the bottom of the ladle, and the impact of the hot water damages the refractory at the bottom. Therefore, it is necessary to repair the damaged part in a timely manner.

In the conventional repair work described above, as shown in FIG. 3, a bucket 2 having a pouring material inside is hung in a ladle 1 by an overhead crane or the like, and is located right above a portion to be repaired. Then, the valve 4 of the discharge port 3 at the lower end is opened, and after pouring a proper amount of pouring material, the worker 5 enters the ladle 1,
The pouring material charged by the rod-shaped vibrator 6 is vibrated and filled, or the bucket 2 is hung in the ladle 1 in the same manner as described above as shown in FIG. 4, and the pouring material is discharged from its discharge port 3. After throwing in, the vibrating plate 7 is hung in the ladle 1 by an overhead crane or the like, and the pouring material is vibrated by the vibrating plate 7 to be filled. 3 and 4
Reference numeral 8 indicates a control panel of the vibrator 6.

[0004]

However, in any of the prior arts shown in FIGS. 3 and 4, the bucket 2 has a ladle 1
Since it is suspended inside, the overhead crane will be dedicated during the construction period, which will limit other work using the overhead crane in the same yard and hinder the progress of other work. There is a problem.

In the case of FIG. 3, since the worker 5 must enter the ladle 1 to perform the vibration work, it is not easy to enter and exit the ladle 1, and the bucket is lifted and hung by a crane according to the safety standard. It must be out of the ladle 1 while it is in operation, the construction amount is 5t, and the mixer capacity is 1t.
If so, it is necessary to go in and out five times, which is not easy.

Further, the filling work of the pouring material is performed by the worker 5
Since it is carried out by the vibrator 6 on hand, not only a high level of technology is required for uniform construction, but it is also inefficient in terms of work efficiency.

On the other hand, in the case of vibrating and filling by using the vibrating plate 7 as shown in FIG. 4, the ladle 1 is used in order to reduce the entrainment of slag at the end of the molten metal outflow from the ladle 1 to the tundish. Because of the tilted outflow and the positional relationship between the ladle 1 and the tundish at the time of outflow, the outflow port 9 is opened near the side wall. It is said that the pouring material filling portion (laying portion) between the nozzle receiving brick 11 and the nozzle inevitably becomes a corner portion. Therefore, it is very difficult to throw the pouring material into this portion and vibrate it by the vibrating plate 7. There's a problem.

In view of the above, the present invention allows an appropriate amount of pouring material to be uniformly introduced into a required portion of a ladle without using existing equipment such as an overhead crane, and an operator can enter the ladle. An object of the present invention is to provide a pouring material filling device for the bottom portion of a ladle that enables unmanned and uniform filling of important points without any operation.
